7 Application filed February 25, 1922. Serial No. 539,088.

To all whom it may concern Be it known that l, OswALo SoHLAUPrrZ, acitizen of the Unitec States, and a resident of the city of Canton, inthe county of Stark and State of ()hio, have invented a new and usefulimprovement in Presses, of which the following is a specification.

My invention relates to presses in which an article is mounted on thebed of the press and is acted on'by a die that is secured to the end ofa plunger. The invention has for its principal objects to provide meansfor easy adjustment of said press for working on articles of differentsizes and to accommodate articles of slightly varying sizes without thenecessity for adjusting the press. The invention consists principally ina yieldable seat for the work and in means for varying the pressure atwhich said seat will yield to the force of the plunger. The inventionfurther consists in the parts and combinations of parts hereinatterdescribed and claimed.

in the drawing, which forms part of this specification and wherein likereference numerals indicate like parts wherever they occur,

Fig. 1 is a side elevation of a press embodying my invention, certainparts being shown in section;

Fig. 2 is a part end elevation and part sectional view along the line2-2 in Fig. 1; and

Fig. 3 is a sectional view along the line 8-3 in Fig. 1.

It is common practice to stamp marks of various kinds in the end of aroller bearing cup or the like, by means of a die 1 that is secured atthe end ot the reciprocating plunger 2 of a suitable press thatcomprises a base or pedestal 3 and bed 4;. Obviously, it articles ofdiiierent heights are to be marked in one press, numerous adjustmentsare necessary. Heretofore such adjustments have required changing thestroke of the plunger or raising or lowering the bed of the press, whichoperations are rather diiii- (ult and do not permit of nice adjustmentof the plunger stroke. A turther disadvantage of ordinary presses isthat the cup or the like is seated on rigid bed and is liable to bedamaged by the sudden impact of the plunger.

According to the present invention, the cup is placed on a yieldable orfloating seat 10 that is mounted in the bed 4 of the press. Preferablysaid seat 10 is provided with a shank portion 11 that its in a tubularmember 12 that is mounted in a suitable hole in the bed of the press.The tubular member 12 is provided with a circumferential rib or flange13 whereby it is secured to the underside or" the bed as by bolts 14-.The lower end of the shank 1.1 of the floating seat 10 rests on theshort arm of a lever 15 which is pivotally secured to the projectinglower end of the tubular member 12. Said tubular member is provided witha suitable opening into which the end of lever 15 extends. The end 0;lever is i'oriiied into a suitable seat 16 to receive the lower end ofthe shank 11 of the floating seat. The long armv oi the lever 15 isprovided with a suitable knii'e edge 17 at the end which contacts withthe lower edge of a second lever 18 that is pivotally secured to asuitable projection 19 on the underside of the bed i of the press andwhich extends in substantially the same plane as the first lever 15. Thesecond lever 18 is provided with a plurality oi notches 20 along itsupper edge. in one ot said notches rests a shackle 21 whose lower end isprovided with a downwardly extending rod 22 having a threaded endportion on which is mounted one end of a turnbuckle 23. The lower end ofsaid turnbuckle 23 is secured to the threaded upper end of a rod 24 towhose lower end is secured one end oi a coil spring 25. The other end ofsaid coil spring is suitably secured to the base 3 of the press.

The operation of the device is as follows.-

A cup or other article 26 to be marked is placed on the yieloable seat10 in position to be struck by the die 1 on the downward stroke of theplunger 2. When the cup is struck; by the die, the yieldable seat 10will yield to an extent permitted by the spring 25 which, operatingthrough the levers 15 and 19 tends to hold said seat in its upper mostposition. The upward movement of the seat 10 limited as the arm of thelever 15 strikes the wall oi the tubular member 12. The parts areadjusted so that the seat 10 will cease to yield before the end of thedownward stroke of the plunger 2, and thus the die will imprint its markin the end of the cup 26 or the like. If it is desired to imprint adeeper mark in the end of the cup or if a smaller cup is to be stamped,the point at which the spring overcomes the force of the plunger may bechanged by turning the turnbuckle 23 or by moving the shackle to adifferent notch of the second lever. In the drawing, said shackle isshown in the outmost notch, in

dicating that the very small article.

The hereinbefore described press permits press being used on a 'easy andaccurate adjustment of the seat on -Jvlii0h the articleto be stamped ismounted.

lt provides a yielding seat for said article,

relates particularly to yieldable means for.

supporting the article in the press, and may be used in presses ofentirely different kinds from that .shownin the drawings. Numerouschanges may be made without departing from my invention and I do notwish to be limitedto the precise construction shown.

lVhat I claim is:

1. In a press of the kind set forth, a seat or the work, a lever thathas one arm formed into asupport for said seat, second lever disposedabove the outer end. of said first lever and engaged thereby meansC01111)l.i+ a sprin for depressing the end of said secondlever, therebyholding said seat in its uppermost position, and means for adjusting thepull oi? said spring onsaid lever.

Q. In a press oi? the kind set forth, a yieldable seat for the work,said seat having a shank portion, a lever whose short arm is formed-intoa support for the end oi the shank portion of said yieldaole seat, asecond lever disposed above the outer end of said first lever andengaged thereby and means comprising a spring for depressing the end ofsaid second lever.

3. In a press of the kind set forth, a yieldable seat for the Work, saidseat having a shank portion, a lever whose short arm is formed into asupport for the end otthe shank portion of. said yieldable seat, asecond lever disposed above the outer end of said first lever andengaged thereby, and means tending to depressthe end of said secondlever.

4. In a press of the kind set forth, a yieldable seat for the work, saidseat having a Shank portion,,a lever whose short arm is iormed into asupport for the end of the shank portion of said yieldable seat, asecond lever disposed-above the outer end of said first lever andengaged thereby and means for depressing the end of saidsecond lever,said means comprising a shackle enaging said lever, a'spring secured tothe ease of the press, rods secured to and ex tending towards each otherfrom said shackle and spring, respectively, and a turnbuckle connectingsaid rods.

5. Ina press of the kind set forth, a yieldable seat for the work, saidseat having a shank portion, a lever whose short arm is" formed into asupport for the end of the shank portion of said yieldable seat, asecond lever disposed above the outer end oil said first lever andengaged thereby and means for depressing the end of said second lever,said means comprising a shackle engaging said lever, a spring secured tothe base of the press, rods secured to and extending towards each otherfrom said shackle and spring, respectively, and a turnbuckle connectingsaid rods, said lever having a plurality of notches in which a saidshackle may be disposed. i

6. ln a press of the kind set :torth, a yieldable seat for the work,said seat having a shank portion, a lever whose shortarm is formed intoa support for the end of the shank portion of said yieldable seat, asecond leverdisposed above theouter end of said first lever and engagedthereby, and

means tending to depress the end of said second lever, said meanscomprising a shackle engaging said lever, a spring secured to the baseof the press and means connecting said shackle and spring.
